Ashleigh Barty in line to break into the world’s top 10 for the first time after she beat Kiki Bertens to reach the last eight of the WTA’s Miami Open. The Australian No 1 dropped the first set against her seventh-seeded opponent but dug deep to prevail 4-6, 6-3, 6-2.

The win secured Barty, the 12th seed, a first appearance in the last eight of a WTA premier mandatory event – the four biggest tournaments outside of the grand slams and the season-ending WTA finals.
